摘要： A problem to be solved of the present invention is to provide a particulate water-absorbing agent which not only ensures the many conventional physical properties (absorption rate, centrifuge retention capacity, absorbency against pressure, particle size distribution etc.) but also prevents odor which is generated after the resin is swollen by absorption. The water absorbent agent of the present invention therefore does not cause odor in actual use. As a result of intensive study of the foregoing problem, the present invention offers a way of controlling a specific odor component, which is generated from impurities and/or by-product derived from the raw material, after the high temperature process. In this way, the present invention successfully provides a water absorbent agent not causing odor after the resin is swollen by absorption.
